Abstract
Es wird ein Halbleitermodul mit einer rauschunterdrückenden Wirkung, die durch Minimieren einer Rauschstromschleife verstärkt wird, bereitgestellt. Ein Halbleitermodul (2) umfasst: einen Schaltungsblock einschließlich ein isolierendes Al-Substrat (41), auf einer Oberfläche des isolierenden Al-Substrats gebildete Schaltkreisstrukturen (42, 42a) und Leistungshalbleiterchips (43, 44); und einen Wärmespreizer (47), der auf der anderen Seite des isolierenden Al-Substrats (41) gebildet ist. Die Schaltkreisstrukturen (42), an die das Maximalpotential und das Minimalpotential im Schaltungsblock angelegt werden, sind elektrisch mit dem Wärmespreizer (47) über Kondensatoren (45, 46) und einen Pin (50), die durch eine Schaltkreisstruktur (42a) angeordnet sind, und das isolierende Al-Substrat (41) verbunden. Daher fließt ein durch eine Potentialänderung in den Schaltkreisstrukturen im Schaltungsblock und parasitäre Kapazitäten zwischen den Strukturen und dem Wärmespreizer verursachter Rauschstrom durch eine minimale Stromrauschschleife einschließlich den Kondensatoren (45, 46) und den Pin (50).There is provided a semiconductor module having a noise suppressing effect which is amplified by minimizing a noise current loop. A semiconductor module (2) comprises: a circuit block including an Al insulating substrate (41), circuit patterns (42, 42a) formed on a surface of the Al insulating substrate, and power semiconductor chips (43, 44); and a heat spreader (47) formed on the other side of the insulating Al substrate (41). The circuit structures (42) to which the maximum potential and the minimum potential are applied in the circuit block are electrically connected to the heat spreader (47) via capacitors (45, 46) and a pin (50) arranged through a circuit structure (42a). and the insulating Al substrate (41). Therefore, a noise current caused by a potential change in the circuit patterns in the circuit block and parasitic capacitances between the structures and the heat spreader flows through a minimum current noise loop including the capacitors (45, 46) and the pin (50).

Technische AufgabeTechnical task
Bei einem herkömmlichen Halbleitermodul wird Rauschen, das durch Schaltungssteuerung einer Leistungshalbleitervorrichtung erzeugt wird, durch einen externen Kondensator umgeleitet und mit Masse verbunden, um reduziert zu werden. Außerdem wird bei dem herkömmlichen Halbleitermodul ein Wärmespreizer elektrisch von einem Schaltungsblock durch ein isolierendes Al-Substrat hinsichtlich direkter Ströme isoliert. Bei dem herkömmlichen Halbleitermodul ist jedoch eine Schaltkreisstruktur kapazitiv mit dem Wärmespreizer gekoppelt (durch parasitäre Kapazitäten
Die vorliegende Erfindung wurde in Anbetracht der oben beschriebenen Probleme gemacht und zielt darauf ab, ein Halbleitermodul bereitzustellen, das eine rauschreduzierende Wirkung hat, die durch Minimieren einer Rauschstromschleife verstärkt wird.The present invention has been made in view of the problems described above and aims to provide a semiconductor module having a noise reducing effect that is enhanced by minimizing a noise current loop.
Lösung der AufgabeSolution of the task
Gemäß der vorliegenden Erfindung wird zum Lösen der oben genannten Aufgabe ein Halbleitermodul bereitgestellt, das umfasst: einen Schaltungsblock einschließlich eine elektrisch isolierende Schicht, eine Vielzahl von Schaltkreisstrukturen, die auf einer leitfähigen Platine oder Folie auf einer Oberfläche der elektrisch isolierenden Schicht gebildet sind, und Leistungshalbleiter, die auf den Schaltkreisstrukturen angeordnet sind; und einen Wärmespreizer, der aus einer leitfähigen Platine auf einer weiteren Oberfläche der elektrisch isolierenden Schicht gebildet ist. Bei diesem Halbleitermodul ist mindestens eine der Schaltkreisstrukturen über die elektrisch isolierende Schicht durch einen Kondensator elektrisch mit dem Wärmespreizer verbunden.According to the present invention, in order to achieve the above object, there is provided a semiconductor module comprising: a circuit block including an electrically insulating layer, a plurality of circuit patterns; formed on a conductive board or film on a surface of the electrically insulating layer, and power semiconductors disposed on the circuit patterns; and a heat spreader formed of a conductive board on another surface of the electrically insulating layer. In this semiconductor module, at least one of the circuit patterns is electrically connected to the heat spreader through the electrically insulating layer through a capacitor.
Gemäß diesem Halbleitermodul, da der Kondensator derart angeordnet ist, dass die Schaltkreisstruktur und der Wärmespreizer elektrisch durch die elektrisch isolierende Schicht verbunden sind, wird die Rauschstromschleife minimiert.According to this semiconductor module, since the capacitor is arranged such that the circuit structure and the heat spreader are electrically connected through the electrically insulating layer, the noise current loop is minimized.
Vorteilhafte Wirkungen der ErfindungAdvantageous Effects of the Invention
Das Halbleitermodul mit der oben beschriebenen Konfiguration ist vorteilhaft im Minimieren der Rauschstromschleife, da es möglich wird, den Effekt der Rauschreduktion zu verstärken. Außerdem, da das Halbleitermodul selbst eine rauschreduzierende Wirkung hat, ist es leicht möglich, die Größe des Wechselrichters zu reduzieren und den Rauschpegel ohne Hinzufügen oder Ändern eines Vorgangs während der Herstellung zu reduzieren.The semiconductor module having the above-described configuration is advantageous in minimizing the noise current loop since it becomes possible to enhance the effect of noise reduction. In addition, since the semiconductor module itself has a noise reducing effect, it is easily possible to reduce the size of the inverter and reduce the noise level without adding or changing a process during manufacturing.
